Unfortunately we've had to delay the upgrade pre-purchases a couple of days while we work out a way to automatically check upgrade eligibility (it would be a ton of manual work otherwise). Very sorry about the delay and we really appreciate your patience. We're working as fast as we can to get this set up!

P.S. Our business is still technically based out of the UK, but Matt and I are in California, Pacific Time. It's early afternoon for us, a perfect time for a pre-release launch.

Yes C-A, as described on the pre-release page: http://planetside.co.uk/buy/buy-terragen-3"Terragen 3 is currently available for purchase as a pre-release beta. When you purchase, you will gain early access to beta versions of Terragen 3 which will be updated on an ongoing basis up to and including the final public release. You will also be entitled to standard Terragen 3 updates through the entire 3.x series."
